DISH-WASHING MACHINE.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed June 28, 1911. Serial No. 635,857.

' To all whom it may concern:

Be it known that I, JEAN BAPTISTE LA- PLACE, a citizen of the Republic of France, residing at Spokane, Washington, United States of America, have invented certain new and useful Improvements in Dish-.

Washing. Machines; and I do hereby declare thatthe following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to'dish washing machines.

In order to more clearly disclose struction, operation, and use of the invenpanying drawings forming part of the present application.

Throughout the several figures of the drawings like reference characters designate the same parts.

In the drawings: Figure 1 is a vertical, longitudinal, cross section through the complete machine; Fig. 2 is a side elevation of the same; Fig. 3 is a view similar to Fig. 2, showing the opposite side; Fig. 4 is an enlarged sectional view through the lower rear part of the machine; and Flg. 5 is a perspective view of one of the guide rollers.

The main object of the invention is to provide a machine into which the used dishes may be successively fed, washed, and dried, and then delivered.

Referring. to the drawings in detail, 1 indicates a large casing adapted to house or inclose all of the working parts. At one end of the casing is supported a trough or other receptacle 2 in which is revolubly mounted a spiral or screw conveyer 3 which may be operated either by hand or by power, and in any suitable and well known manner. This conveyer is adapted to deliver the dishes from trough 2, through a chute 3 in the rear wall of easing 1, and on to the upper run of a continuously moving belt or apron 4. This belt, preferably, consists of a number of slats flexibly connected so that solid matter either washed or brushed from the dishes may pass between the slats and drop into the removable receptacle 5, below. Directly above the upper run of the belt 4 and in line with the travel of thedishes thereon is a continuously rotating brush 6 which may be driven through any suitable shaft or the con-,

- cess to t gearing connections. At the forward end of the traveling apron 4 is arranged a chute 7 leading into a middle compartment 8 and terminating directly above the upper run of a continuously moving, inclined apron 9 similar to apron 4. The chute 7 is provided with side guards 10 to prevent the dishes from slipping sidewise therefrom. The

chute is formed of widely separated longitudinal slats to permit the upward passage of the bristles of a lower rotating brush 11. The upper face of the dish is, at. the same time, subjected to the scrubbing action of a continuously rotating brush 12. Brushes 11 and 12 rotate in opposite directions in order to get the full cleaning efi'ect. They ma Y be rotated by any suitable and well known s aft and gear connections. The compartment 8 is adapted to contain water to a considerable depth, enough to cover the lower half of the apron 9 and the rotating brushes 11 and 12. From the apron 9, the dishes pass to a chute 13, and from this chute they drop into large box-like trays 14 carried by endless chains which may be driven in any suitable and well known manner. The chains, of course,

are continuously traveling and endless, to

operated in the same manner as trays 14.

From trays 16, the dishes pass to a delivery chute 20 and thence to the outside of the machine. All of the upper part of the casing,

above the partition 21, is heated by a steam pipe 22, or the "like, lying therebeneath. Both the compartment 8 and the following compartment may be supplied with a soap or soap solution from suitable holdersv 23 mounted therein. The fumes from the heated portion of the casing may escape through the pipes or flues 24. Suitable doors maybe I0Vld8d at various points where ace interior of thecasmg or the working parts of the apparatus isrequired. Also, the various 'ournals and bearings of the several drive s afts of the belts and a rons, as

well as the bearings of the shafts or driv-w ing the brushes, may be adequatelylubricated by a well arranged system of pipes and branches. The driving mechanism, as shown in Fig. 3, is the usual belt and pulley arrangement.

It is thought that the Operation and use of the invention will be clear from the preceding detailed description. 4

Changes may be made in the construction, arrangement, and disposition of the several parts of the invention without many way departing from the field and scope of the same, and it is vmeant to include all such within this application wherein only a preferred form has been disclosed.

Having thus fully'deseribed my invention, What I claim as new and desire to secureby Letters Patent'is: I v

, l. A machine of the character described, comprising a casing provided with a receiving chute, a trough mounted adjacent said chute, means for delivering dishes from said trough into saidchute, a belt adapted to receive the dishes from 'said-chute, an inclined apron adapted to receive the'dishes' from the said belt, means for guiding the dishes from the belt to the-apron, a series .dish receiving trays carried by each of separate traveling belts, a plurality) of elt means for guiding the dishes from the'afore said apron to the trays of one of saidbelts, means for guiding the dishes from the trays" of one belt to the trays of thenext-belt', and

means for receiving and guiding the dishes vfrom said belt, means for guiding the dishes from the belt to the apron, means for scrubbing the dishes as they are so guided, a series of separate traveling belts, a plurality of dish receiving trays carried by each belt,

means for guiding the dishes from the aforesaid apron to the trays of one of said belts, means for guiding the dishes from the trays ofone belt to the trays of the next belt, and

means for receiving and guiding the dishes from the trays of the last belt to the outside of the machine. 7 a

In witness whereof I have hereunto set my hand in the presence of two witnesses. JEAN BAPTISTE LAPLACE.
